KNIPEX12 12 14 Precision Insulation Strippers with adapted blades AWG 16/18/20/22/24/26

best wire-strippers I have every used. I have tried other brands of the same type too.I just took off the piece of plastic seemed kinda annoying to use.only con is how they are big if you are working in Extremely tight areas.

These are the strippers to get if you need to strip teflon insulated wire.
